ANCHOR-DRILL.
Specification of Letters Patent.
. Patented July 27,1915.
Application filed January 21, 1914. Serial No. 813,396.
T0 all whom it may concern Be it known that l, Onis K. DUNBAR, a citizen of the United States, residing at Centerville, in the county of Vayne and State of Indiana, have invented a new and useful Anchor-Drill, of which the following is a specification.
It is the ob]- ect of my invention to provide a simple, strong, and inexpensive ground anchor, for use, for instance, in anchoring wireAfences, tents, or other things to the ground, and a simple and eifective drill for making a hole for the reception of this anchor, the anchor being inserted into its hole through part of the drill.`
The accompanying drawing illustrates my invention.
Figure 1 is an elevation of the anchor drill; Fig. 2 is a longitudinal section through the anchor drill; Fig. 3 is a longitudinal section through the tubular member of the anchor drill when in the ground, showing the anchor being inserted; Fig. l is a sectional view showing the anchor in anchoring position in the ground, the drill being entirely removed; and Fig. 5 is a transverse section on the line 5 5 of Fig. 3.
The anchor drill comprises an outer tubular-member 10, conveniently made of gas pipe, and an inner member 11 which is slidable freely within the tubular member 10 and is conveniently an ordinary iron or steel rod. The inner member 11 is provided at its upper end with a weight 13, having a handle 14, the member 11 conveniently being screw-threaded into the lower end of the weight. This lower end of the weight is conveniently counter-bored so that it can lit loosely over a pipe coupling 15 screw-threaded on the upper end of the tubular member 10, such coupling projecting slightly be yond the upper end of the member 10 proper, so that the blows `from the weight 13 will come upon such coupling and not on the end of the pipe 10; this permits the coupling 15, when battered, to be replaced at the cost of a few cents, without necessitating the replacement of the whole pipe 10. 1f desired, a lead cushion 16 may be placed in the counter-bored lower end of the weight 13, for lessening the battering of the coupling 15. The tubular member 10 is conveniently provided near its upper end with a handle 17. The lower ends of both members 10 and 11 are preferably tapered, and the member 11 is sufficiently longer than is the member 10 so that when the weight 13 rests against the coupling 15 the lower pointed end 18 of the rod 11 projects slightly below the lower end of the tubular member 10.
In operation, the member 10 is set at the place on the ground where a hole is desired, and the member 11 is reciprocated up and down in the member 10. On each down stroke of the member 11 the weight 13' strikes the coupling 15 and the pointed end of the member 11 strikes the ground, thus forcing both members 10 and 11 down into the ground. This is done with comparative ease even in the hardest earth and in soft rocks, making a clean hole. When the hole has been made to the desired depth, the inner member 11 is withdrawn, leaving the tubular member 10 in place. Then an anchor, which consists of a member 20 which is a section of a tube so that in cross section it is an arch of preferably less than 180O and which is longer than the diameter of the tubular member 10 and is pointed at one end 21 at the crown and at the other end' 21 at the bases of the cross sectional arch and is provided with holes 22 nearer the end 21, and is mounted in the bight of a looped wire 23 passing through the holes 22, is dropped lengthwise through the tubular member 10 by means of such wire, which is bent to lie in the groove formed by the concave side of the anchor 20, the anchor and the looped wire together being smaller in diameter than is the inside of the tube 10, as shown in Fig. 3. Then the anchor 21 has been dropped to the bottom of the hole formed in the ground, the tubular member 10 is pulled up, leav* ing the anchor 20 and wire 23 in the hole, and after such member has been gotten out of the way an upward pull is given on the wire 23. This causes the point 21 to dig into one side of the hole in the ground, and the point 21 to cut upward into the other side of such hole, so that the continued upward pull on the wire 23 eventually brings the member 20 crosswise of the hole, as shown in Fig Ll. Vhen in this position, the anchor will stand a very considerable strain without pulling out. The shorter end of the anchor 2O is prevented from being pulled too far upward, not only by the pressure of the ground above it, but by the bend which was formed on the wire 23 when such wire was bent to make it lie within the anchor 20 as such anchor was being dropped through the tubular member 10.
